IMPROVEMENT IN OIL-CUPS.

To ALL wHoM 1T MAY coNcERN:

Be it known that I, HENRY STANLEY, of St. Louis, in the county of St. Louis, and State of Missouri, have made certain new and useful Improvements in Automatic Oil-Cups; and I do hereby declare that the following is a full and clear description` thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. 1

This invention relates to an automatic oil-cup for lubricating journals or other machinery-bearings. The peculiarities of the invention consist in combining a wooden necking with aglass or metallic cup, and to sundry other details of construction, hereinafter more fully explained.

The advantages of the wooden necking are, that the vparts are more cheaplyeonstructed, and more easily applied to the bearing whereon they are to be used.

To enable those skilled in the art to make and use my improved oil-cup, I will proceed to describe-its construction andoperation.

Figure 1 of the drawings is a central sectional elevation of the'imprved cup. Figure 2 is an elevation of the wooden necking or coupling-piece.

Figure 3 is an elevation oi' the metallic cap or diaphragm which covers the top end of the necking-piece,

and `forms the bottom of the oil-chamber.

The cup, A, may be made of metal, butI prefer to make it of glass, with the top part of" it lreinforced. at a a for the purpose of forming a substantial seat for the plug a whichwill be ground into its seat. The necking or coupling-piece, B, will be of wood, and, as is clearly shown in iig. 2, will have a pi'n or tenon, ZJ, on one end for passing up into and securing it to the cup A, and a similar pin or'tenon, bf, on its other end for attaching it to the bearing-box that is'to be lubricated. The great advantage of using -this wooden piece B consists in the facility with which it may be attached to the bearing-box by whittling oi the pin or tenon b1 so as to tit it to the lubricating-aperture of the bearing-box. The piece being of wood, the aperture In?, through which the oil descends from the cup A to the bearing, will 'necessarily have to be too large for an economical'use of the l-ubricator; hence I place a metallic cap, C, over the top end of the tube b, which cap forms a diaphragm at the bottom of the oil-cup, and between it and the coupling-piece B. Through this diaphragm a small orifice, c, is made ofjust sutiicient size to admit the required amount of lubricant to the bearing. In assembling the parts, some cementing-material or wax will .have to be interposed between the parts A and B, to prevent afleakage of the lubricator` through the-joint.

Having described my invention, what I claim, is-

The combination of the oil-cup A, stoppera, wooden end-piece B, slotted at b2, and capped by the metallic cap C, having the minute perforation c, substantially as her-einbefore set forth.

In testimony of which inventiou,I hereunto set my hand, in presence of- HENRY STANLEY. i
